The superheated steam is generated from the boiler operation at 12 bar pressure. Steam generated \(/ \mathrm{kg}\) of coal burnt is \(10 \mathrm{~kg}\). Coal burnt \(=300 \mathrm{~kg} / \mathrm{h}\). If the enthalpies of superheated steam and water entering the boiler are \(2935.4 \mathrm{~kJ} / \mathrm{kg}\) and \(150.74 \mathrm{~kJ} / \mathrm{kg}\) respectively, then calculate

(a) Equivalent evaporation

(b) Boiler power.
